微信小程序授权页面,效果图如下
app.js 中的 onLaunch或onShow中加如下代码,如果没授权跳转到授权页面
// 获取用户信息 wx.getSetting({ success: res => { if (res.authSetting[‘scope.userInfo‘]) { // 已经授权,可以直接调用 getUserInfo 获取头像昵称,不会弹框 wx.getUserInfo({ success: res => { // 可以将 res 发送给后台解码出 unionId this.globalData.userInfo = res.userInfo // 由于 getUserInfo 是网络请求,可能会在 Page.onLoad 之后才返回 // 所以此处加入 callback 以防止这种情况 if (this.userInfoReadyCallback) { this.userInfoReadyCallback(res) } } }) }else{ // 未授权,跳转到授权页面 wx.reLaunch({ url: ‘/pages/auth/auth‘, }) } } })
auth.wxml 授权页面结构
<view class="auth"> <image src="https://res.wx.qq.com/wxopenres/htmledition/images/favicon32f740.ico" class="img" mode="aspectFill"></image> <view class="title">微信授权页面</view> <view class="describe">此页面是微信授权页面,点击下方按钮弹出授权或跳转页面</view> <button class="btn" open-type=‘getUserInfo‘ wx:if="{{canIUse}}" bindgetuserinfo=‘onAuth‘>点击微信授权</button> <navigator wx:if="{{!canIUse}}" class="btn" url="/pages/auth/auth" open-type="reLaunch" hover-class="other-navigator-hover">已经授权点击调转</navigator> </view>
